I once did a slate floor in a straw bail house using rough slate so we did a bunch of cutting on it, a wet tile saw works good but the slate has enough oil in it that it makes an oil slick on top of the water after a while and the mud from cutting it can stain, a few cuts is not an issue of course, it's a pretty soft rock so like Ben said, sand paper will take off sharp corners, even a file or rasp will cut it, but it has paper thin layers to it so it can flake off if you are not careful.

My parents have slate black board spaced out from the two walls next to their wood cook stove, functioning as the non combustible material that is required to protect the wall.
